CLEVELAND, O HIO, A CORPORATION OF OHIO.

MEETI G-cur.

Be it known that I, GEORGE E. LEE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement inv Melting-Cups, of

description.

This invention relates to amelting cup and is primarily intended for use in connection-with a feeder attachment used on linotype machines.

This device finds particular utility in con; nection with the feeding device shown in the application of Albert A. Froehlich, Serial No. 7 O6,594,'filed June 29th, 1912.

Generally speaking, the invention comprises the elements and combinations thereof set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a part of this specification, in which Figure 1 is a sectional elevation of my melting cup; Fig. 2 is a partial top plan view; Fig. 3 is a sectional elevation of a modified form of the cup; and Fig. 4 is a artial top plan view of the cup shown in The body of the cup is represented at 1, and is referably, although not necessarily, cylindrlcal in shape. Near the lower portion there is formed in the wall and bottom of the cup an opening 2 which will permit the escape of the material which may be melted within the cup.

The portion of the opening 2 which is formed in the bottom or base of the cup is surrounded by a circular wall 3, which is of little height, and thereby forms a dam so that the melted material before it may escape from thecup, must flow over the wall or dam 3.

Extending inwardly from the wall 1, at a point above the outlet ,2, and substantlally centrally located with respect thereto, is an inwardly extending rib 4. This rib is wedge shaped, with the widest end toward the opening 2. This rib is for the purpose of guiding the material to be melted, as it enters the cup, and keep the material away from the outlet opening 2. The pot is primarily adapted to receive a solid ingot of the material which is to be melted, and if means were not provided, such as the rib 4, the ingot would undoubtedly engage with Specification of Letters Patent.

the dam 3, and so prevent the outflow of material until the material of the ingot had been melted at the point where it may'contact with the dam 3, and this closure of the op'emng2 might cause the material to be backed up within the cup to the point of overflowing.

As before stated, this'cup finds particular utility in connection with an auxiliary metal feeding device for use with linotype mach1nes, and is used in connection with a burner which is adapted to supply heat to the cup upon the bottom portion thereof. -An ingot of metal resting within the cup 1, will of course be melted, as the heat is supphed to the cup, and as soon as suflicient metal has been melted to fill the bottom of the cup and overflow the dam 3, the metal will feed through the opening 2, into the usual melting pot of the linotype machine.

The functioning of the burner, which heats the cup 1, is in such machines usually automatically controlled, so that when it is necessary to supply metal to the melting pot of the. linotype machine, the supply of gas to the burner is established and lgnlted, and as soon as a suflicient of'supply of metal has been given to the melting pot, the supply of gas is automatically turned off, which of course stops the melting of the metal of the ingot which is within the cup 1.

This would leave a supply of metal in the bottom of the cup, into which the ingot would extend, and it has been found that the supply of metal which is thus left in the bottom of the cup usually does not harden before the timeit is necessary to furnish a further supply of metal to the melting pot of the linotype machine, and further, this metal in the bottom of the cup, maintains the bottom of the ingot, between heating periods,

in a condition such that it is not melted but thoroughly heated. Consequently, when the gas is turned on to the burner which heats the cup 1, the supply of metal from the cup will quickly flow because of the condition of the metal within the cup which has just been explained.

In Figs. 3 and 4, the construction of the cup is the same as that shown in Figs. 1 and 2, with the exception that there is no dam around the outlet opening 2.

Having thus described my invention, what ingot of material to be melted, said cup being provided with an outlet opening at one side thereof, and means associated with the said cup, for engaging the ingot to guide the ingot away from the outlet opening.

2. A melting cup adapted to receive an ingot ofmaterial to be melted, said cup being provided with an outlet opening, a projection carried upon the interior of the cup above the opening, for engaging the ingot to guide the ingot away from the opening.

3. A melting cup adapted to receive material to be melted in solid form, said cup being provided with an outlet opening, a wedge-shaped ridge upon the interior wall of said cup above the opening, the widest end of said ridge being adjacent the said opening.

4. Amelting cup adapted to receive ma-' terial to be melted in solid form, said cup ,being provided with an outlet opening in one side thereof and a dam surrounding said opening for the purpose described.

unease 5. A melting cup adapted to receive an ingot of material to be melted, said cup being provided with an opening, a dam upon the inside of the cup and surrounding the said opening, and means upon the interior of said cup above the opening for guiding the ingot supplied in said cup away from the opening.

-6. A melting cup adapted to receive material to be melted in solid form, said cup being provided with an outlet .opening, a dam upon the interior of said cup and surrounding the opening, and a projection carried by the cup above the said opening for the purpose of directing the material supplied to said cup away from the opening.

In. testimony whereof, I hereunto afix my signature in the presence of two witnesses.
